That is, the mobile deviceloss prevention system may be added to the mobile device as an add-onapplication or it may be deeply incorporated into the mobile device. Themobile device loss prevention system uses environmental parameters ofthe mobile device to predict whether the mobile device is lost and thenperforms certain actions to notify the user or authorized person of thelost prediction. The user or authorized person can then take steps torecover the lost mobile device, thereby preventing loss of the mobiledevice. This system and process helps prevent loss of the mobile deviceother than for a temporary time period.

Environmental elements 340 include NFC/WPAN 342, WLAN 344, GPS 346,camera 348, microphone 350, sensors 352, function monitor 354 and other356. NFC/WPAN (near field communications/wireless personal area network)342 includes the capability to communicate with other devices that areeither with or in the near proximity of the user. This can include othermobile devices the user may be carrying such as a remote earpiece, atablet, a tag, or other mobile device. For example, the user may carry apassive tag in his or her wallet for use such as described below. WLAN(wireless local area network) 344 includes the capability to communicatewith wireless routers and other devices in the local area. Suchcommunications include identifying information which can be utilized todetermine the general location of the mobile device. For example, a homewireless router is easily identified and can be used to determine thatthe mobile device is not lost. GPS (global positioning system) 346 isable to determine the location of the mobile device anywhere in theworld so long as the GPS has a sufficient signal from multiplesatellites. If the mobile device is indoors, the GPS function may notfunction properly.

For example,facial recognition technology can be utilized to identify the user orthe user's family and friends. Microphone 350 can periodically or ondemand sample ambient sounds near the mobile device. This can includewhen a phone call is being made if the mobile device is a mobile phone.These sounds can be analyzed for determining whether familiar sounds orpersons are nearby.

The accelerometer and inclinometer can also beutilized to identify the current holder of the phone through gaitanalysis or holding patterns. A thermometer may be utilized to determinethe ambient temperature. Camera 348, microphone 350 and sensors 352 areambient environment sensing elements 353 and can be utilized todetermine the ambient conditions of the mobile device. Many other typesof sensors may be similarly utilized.

Flash 364, such as a camera or otherlight flash, may generate a series of light flashes to alert a nearbyperson that the mobile device may be lost and to the location of themobile device. Speaker 362 and flash 364 are vicinity action elements365 for alerting persons in the vicinity of the mobile device. SMS/MMS(short message service/multimedia message service) 366 can generate atext or other message to a predesignated device to alert the user orother authorized person.

FIG. 4 is a flow diagram of the mobile device loss prevention system inaccordance with a first embodiment. In a first step 400, the mobiledevice loss prevention system samples the environmental conditions ofthe mobile device. This can include determining the relative or absolutelocation of the device, determining the ambient conditions, andmonitoring the operational functions of the mobile device. Determiningthe location can include identifying any nearby devices through NFC orWPAN, identifying any routers or other wireless devices through WLAN, ordetermining the geographic location of the device through GPS.Determining the ambient conditions can include taking a picture,listening to ambient sounds, taking the temperature, determining if themobile device is being moved, and determining the orientation of thedevice. Monitoring the operational functions of the phone can includemonitoring the user using the mobile device such as user entry onto atouch screen (e.g. text entry, menu selection) and other useractivities. Many of the aforementioned actions can be occurringcontinuously as a monitoring function, but may be sampled periodicallyor as needed. Such sampling may be different for different environmentalconditions.

In a second step 405, the raw sampled data is analyzed and parametersare generated from the analytical results, thereby generating a currentset of environmental parameters. These environmental parameters caninclude absolute or relative measures such as location, probabilityanalysis of whether the current user or holder of the phone is the owneror other authorized person, or other analytical results which can becompared with past analytical results. This current set of environmentalparameters is then time stamped and stored in historical data in step408. The raw data may also be stored with the parameters if desired,although that amount of information may be excessively large for localstorage.

In a fourth step 410, the current set of environmental parameters iscompared to the historical data. This comparison can include acomparison to averages of historical data (stored in statisticalparameters) as well as to specific environmental parameters previouslystored in historical data. Then in step 415, a determination is madewhether there is a significant difference between the current set ofenvironmental parameters and the historical data. A significantdifference is the probability of the device being lost exceeding athreshold. This determination can include statistical analysis of thedeviation from the averages as well as determining whether there havebeen any close matches to specific sets of environmental parameters inthe historical data. If there is not a significant difference, thenprocessing returns to step 400, otherwise the mobile device may be lostand processing continues to step 420.

There are many possible examples of potential significant deviations.For a first example, the mobile device lost prevention system may detectunknown voices without detecting known voices in combination with thephone being in an unfamiliar location. That is, the user may have leftthe phone on a table in a restaurant. For another example, the ambienttemperature may be quite low and the phone in an unusual location. Thismay indicate that the phone is outside and not in the pocket or hand ofthe user such as if the user dropped the phone while jogging. Each ofthese examples could create unusual conditions as reflected in theenvironmental parameters detected by the mobile device loss preventionsystem.

In step 420, a first set of actions are performed in response to thedetermination that the mobile device may be lost. This set of actionsmay be set forth in the configuration database. The mobile device mayinitially generate and audible sound such as a beep and flash the mobiledevice light flash to alert the user that the mobile device may be lost.The beeping and flashing can also alert others if someone other than therightful owner of the phone is taking the phone. This alert can beturned off by the user logging into the mobile device. This prevents anunauthorized person from turning off the alert. The alert may betemporarily suspended by pressing a specific key or button to allow theuser time to log into the mobile device. Otherwise, in case of a falsepositive, the user may be in an environment that continuing the alertcould cause discomfort of the user and others. Then in step 425, it isdetermined whether the user has logged into the mobile device within apredetermined time. If yes, then processing continues to step 450,otherwise processing continues to step 430.

In step 430, a second set of actions are performed in response to thedetermination that the mobile device may be lost. This set of actionsmay also be set forth in the configuration database. The mobile devicemay send a message to another device of the user or other authorizedperson through one or more communications including text, email or phonecall. The message can include information that the mobile device may belost and include any locational information or other information (suchas temperature) which may be useful in locating the mobile device. Asbefore, this alert can be turned off by the user logging into the mobiledevice. Then in step 435, it is determined whether the user has loggedinto the mobile device within a predetermined time. If not, thenprocessing returns to step 430 to repeat the message with any updatedlocational information, otherwise processing continues to step 450.

In step 450, the user has logged into the mobile device, cancelling anyalerts. In this step, the user is queried whether the device had beenlost. The user response is determined in step 455. If yes, then in step460 the current set of environmental parameters stored in historicaldata are marked as indicating a mobile device is lost so that thoseparameters are not used in the future to indicate a normal set ofenvironmental parameters. If no, then in step 465, the statisticalparameters are updated with the current set of environmental parametersto help avoid a similar false positive. Processing then returns to step400.

FIG. 5 is a flow diagram of the mobile device loss prevention system inaccordance with a second embodiment. In this embodiment, there isgreater granularity of statistical analysis and more use of prior dataregarding mobile device lost prediction than in the first embodiment.Statistical analysis is the practice or science of collecting andanalyzing numerical data in large quantities such as for the purpose ofinferring proportions and probabilities in a whole from those in arepresentative sample.

Due to the lack of initial historical data, the mobile device lossprevention system may initially generate many false positives and falsenegatives when predicting the mobile device is lost. This can bemitigated by the use of dummy statistical data initially, which can thenbe supplanted with actual historical data over time. This dummystatistical data can be developed based on actual data of other users orwith artificial data. The user may be queried about his or heractivities when acquiring the mobile device to tailor the dummy data tothe user.

In a first step 500, the mobile device loss prevention system samplesthe environmental conditions of the mobile device. This can includedetermining the relative or absolute location of the device, determiningthe ambient conditions, and monitoring the operational functions of themobile device. Determining the location can include identifying anynearby devices through NFC or WPAN, identifying any routers or otherwireless devices through WLAN, or determining the geographic location ofthe device through GPS. Determining the ambient conditions can includetaking a picture, listening to ambient sounds, taking the temperature,determining if the mobile device is being moved, and determining theorientation of the device. Monitoring the operational functions of thephone can include monitoring the user using the mobile device such asuser entry onto a touch screen (e.g. text entry, menu selection) andother user activities. Many of the aforementioned actions can beoccurring continuously as a monitoring function, but may be sampledperiodically or as needed. Such sampling may be different for differentenvironmental conditions.

In a second step 505, the raw sampled data is analyzed and parametersare generated from the analytical results, thereby generating a currentset of environmental parameters. These environmental parameters caninclude absolute or relative measures such as location, probabilityanalysis of whether the current user or holder of the phone is the owneror other authorized person, or other analytical results which can becompared with past analytical results. This current set of environmentalparameters is then time stamped and stored in historical data in step508. The raw data may also be stored with the parameters if desired,although that amount of information may be excessively large for localstorage.

In a fourth step 510, the current set of environmental parameters iscompared to statistical parameters derived from historical data for eachtype of environmental parameter detected to determine deviations fromthe norm. The statistical parameters can include averages with standarddeviations, probabilities based on prior historical data, and otherstatistical measures which can be compared with the currentenvironmental parameters. A probability that the mobile device is lostis based on these individual environmental parameter deviations is thengenerated in step 513.

Then in step 515, the current set of environmental parameters iscompared to detected correlations developed from historical data todetermine deviations from the norm. For example, historical data maydemonstrate a significant correlation between ambient temperature andmotion. That is, whenever the mobile device is outside in cooler orwarmer temperatures, the user is moving such as by exercising. Thesecorrelations may also be time sensitive. That is, the correlationdescribed above may occur in the morning, but not the evening. Aprobability that the mobile device is lost is based on environmentalparameter deviations from these correlations is then generated in step518.

In step 520, the current set of environmental parameters is compared toprior historical samples stored in historical data to determine how manytimes which there have been similar environmental parameters. From thisinformation, such as a percentage of samples that are similar (or not),a statistical probability that the mobile device is lost can bedetermined based on this similarity sample information in step 523.

In step 525, the current step of environmental parameters is compared toprior historical incidents stored in historical data where the mobiledevice was lost, as confirmed by the user, to determine how many timeswhich there have been similar environmental parameters. This informationcan then be used to determine a statistical probability that the mobiledevice is lost is based on similarity with prior lost environmentalparameters in step 528.

Then in step 530, the above described probabilities that the mobiledevice is lost are weighted and combined to generate an overallprobability that the mobile device is lost. Other forms of combiningprobabilities can be utilized including weighting the probabilitiesbased on statistical confidence in each individual probability. Then instep 533, the lost probability is reduced if certain parameterconditions are identified. For example, if the device is plugged in anda known voice is heard, then the probability may be reduced based onprior knowledge or other information beyond the historical samples. Foranother example, if the calendaring function of the mobile deviceindicates a change in location, then more movement than normal may beexpected.

Once the final probability that the mobile device is lost has beendetermined, then in step 535 an overall determination is made whetherthere is a significant difference between the current set ofenvironmental parameters and the historical data (including statisticaldata derived from that historical data). A significant difference isindicated by the probability of the device being lost exceeding athreshold. The threshold can include statistical confidence levels suchthat certain confidence levels of a given lost probability are needed toexceed the threshold. If there is not a significant difference, thenprocessing returns to step 500, otherwise the mobile device may be lostand processing continues to step 540.

There are many possible examples of potential significant deviations.For a first example, the mobile device lost prevention system may detectunknown voices without detecting known voices in combination with thephone being in an unfamiliar location. That is, the user may have leftthe phone on a table in a restaurant. For another example, the ambienttemperature may be quite low and the phone in an unusual location. Thismay indicate that the phone is outside and not in the pocket or hand ofthe user such as if the user dropped the phone while jogging. Each ofthese examples could create unusual conditions as reflected in theenvironmental parameters detected by the mobile device loss preventionsystem.

In step 540, a first set of actions are performed in response to thedetermination that the mobile device may be lost. This set of actionsmay be set forth in the configuration database. The mobile device mayinitially generate and audible sound such as a beep and flash the mobiledevice light flash to alert the user that the mobile device may be lost.The beeping and flashing can also alert others if someone other than therightful owner of the phone is taking the phone. This alert can beturned off by the user logging into the mobile device. This prevents anunauthorized person from turning off the alert. The alert may betemporarily suspended by pressing a specific key or button to allow theuser time to log into the mobile device. Otherwise, in case of a falsepositive, the user may be in an environment that continuing the alertcould cause discomfort of the user and others. Then in step 543, it isdetermined whether the user has logged into the mobile device within apredetermined time. If yes, then processing continues to step 550,otherwise processing continues to step 545.

In step 545, a second set of actions are performed in response to thedetermination that the mobile device may be lost. This set of actionsmay also be set forth in the configuration database. The mobile devicemay send a message to another device of the user or other authorizedperson through one or more communications including text, email or phonecall. The message can include information that the mobile device may belost and include any locational information or other information (suchas temperature, pictures of the surroundings, name of closest WLAN,etc.) which may be useful in locating the mobile device. The GPS unitmay be turned on to determine the geographic location of the mobiledevice. Other actions can be taken to maximize the probability ofnotifying the owner or other authorized person of the location of themobile device including sending logs of the handler's activities withthe phone. As before, this alert can be turned off by the user logginginto the mobile device. Then in step 548, it is determined whether theuser has logged into the mobile device within a predetermined time. Ifnot, then processing returns to step 545 to repeat the message with anyupdated locational information, otherwise processing continues to step550. The first and second set of actions may be configurable by theuser. For example, the first set of actions may not be performed or maybe performed more vigorously depending on the configuration or thecircumstances. For another example, if it is apparent that the mobiledevice has just been absconded, then the beeping and flashing may be atmaximum intensity and for a long duration without allowing the handlerto suspend the alert. Furthermore, the second set of actions may beperformed concurrently with the first set of actions.

In step 550, the user has logged into the mobile device, cancelling anyalerts. In this step, the user is queried whether the device had beenlost. The user response is determined in step 552. If yes, then in step554 the current set of environmental parameters stored in historicaldata are marked as indicating a mobile device is lost so that thoseparameters are not used in the future to indicate a normal set ofenvironmental parameters. If no, then in step 556, the statisticalparameters are updated with the current set of environmental parametersto help avoid a similar false positive. Processing then returns to step500.

Many other configurations may be implemented in alternative embodiments.For example, the historical data may be periodically uploaded to acentral server for performing detailed statistical analysis fordetermining the statistical parameters and perhaps modifying theconfiguration parameters. This provides for a more distributed system ofprocessing environmental parameters.

FIG. 6A through 6C are block diagrams of types of database records inwhich various embodiments may be implemented. A record is a set ofinformation within a domain or database that establishes a relationshipbetween a set of data or data elements. A record may be a separate entryinto a database, a set of links between data, or other logicalrelationship between a set of data.

FIG. 6A is a block diagram of a record 600 stored in a historical datadatabase. There is a single record for each recorded set ofenvironmental parameters for a mobile device environmental conditionsample, although alternative embodiments may differ. Raw data is notstored in this database, although alternative embodiments may do so. Allparameters stored in this database are considered environmentalparameters, although they are categorized by type as describe herein.Each set of parameters described below may contain more than oneparameter.

Each record 600 includes a timestamp 601, location parameters 602,ambient parameters 603, operational functionality parameters 604,derivative parameters 605, other parameters 606, and a lost flag 607indicating whether the sampled environment was an actual mobile devicelost as confirmed by the user.

Location parameters 602include a set of parameters regarding the relative or absolute locationof the mobile device. Ambient parameters 603 include a set of parametersdescribing the ambient conditions of the mobile device such astemperature and motion. Operational functionality parameters 604 includea set of parameters regarding the functionality of the mobile devicesuch as typing speed or angle of finger placement of the user on themobile device. Derivative parameters 605 include a set of parameterswhich may be derived from the foregoing sets of parameters. For example,based on several parameters, a predictive value can be made of whetherthe holder of the mobile device is the user. Other parameters 606include a set of environmental parameters other than described above.Lost flag 607 is a flag generated when the user confirms that thisparticular sample corresponds to conditions when the mobile device waslost.

FIG. 6B is a block diagram of a record 620 stored in a configurationparameters database. Record 620 includes a variety of informationutilized to configure the operation of the mobile device loss preventionsystem. Each of the below described elements may include multiple setsof information utilized to configure the loss prevention system. Record620 includes user information 621, authorized person information 622,location information 623, other device information 624, lost probabilityweighting 625, probability reduction parameters 626, thresholdprobability 627, first actions 628 and second actions 629.

User information 621 provides a variety of information regarding theuser including name, contact information, facial recognition parameters,voice recognition parameters, gesturing parameters, etc. Thisinformation can be utilized to recognize the user as well as contact theuser if the mobile device is possibly lost. Authorized personinformation 622 includes similar information to user information 621 forsimilar purposes. For example, a spouse of the user may be an authorizedperson. Location information 623 includes information regarding knownlocations such as the user's home, place of work, WLAN devices at thoselocations, frequented other location information, etc. This informationmay be utilized to determine whether the mobile device is in a knownlocation or an unknown location. This information may also be utilizedto provide information the user or authorized person of the location ofthe mobile device. Other device information 624 includes informationregarding other devices normally utilized by the user including anearpiece, a tag, a tablet or mobile phone, etc.

Lost probability weighting 625 includes the weighting utilized todetermine an overall probability of use or the algorithm utilized todetermine a weighting. Probability reduction parameters 626 includecertain non-historical parameters or combinations of parameters thatindicate that the device is not lost or indicate that it is lost.Threshold probability 627 includes a threshold utilized to determinewhether the determined probability that the mobile device is lost issufficient to take action to contact and notify the user or authorizedperson of the lost prediction. First actions 628 includes the actionstaken when it is determined that the mobile device is lost. Secondactions 629 includes the actions taken when it is determined that themobile device is lost. Alternative embodiments may utilize differentconfiguration parameters. In addition, many other types of configurationparameters may be utilized and stored in this database.

FIG. 6C is a block diagram of records 640 and 660 stored in astatistical parameters database. Records 640 and 660 include informationuseful for performing statistical analysis to determine whether themobile device is lost. This statistical information is generally derivedfrom the historical data. There are two types of records shown in thestatistical parameters database. The first record 640 is used forstoring information regarding different sampled environmental parametersused for statistical analysis. For example, there may be a record forall samples of temperature and another record for all samples oflocation. Record 640 includes sample parameter description 641, sampleparameter distribution type 642, sample parameter average 643, sampleparameter standard deviation 644 and sample parameter number 645. Thesecond record 660 is used for storing information regarding differentcorrelations used for statistical analysis. Record 660 includescorrelation type 661, correlation distribution 662, correlation average663, correlation standard deviation 664, and correlation number 665.

Sample parameter description 641 includes a description of the parametersample. For example, it could include the term temperature if samples ofthe temperature are statistically described in this record. Sampleparameter distribution type 642 includes the type of distribution of theparameter sampled. For example, the result of the sampling may generatea normal curve, a uniform distribution, a bimodal normal distribution, aPoisson distribution, etc. The remaining elements of the record may varydepending on the distribution, but are described as if the sampledistribution is a normal distribution. Sample parameter average 643includes the average of all the samples of the parameter. Sampleparameter standard deviation 644 includes the standard deviation of allthe samples of the parameter. Sample parameter number 645 includes thenumber of samples used to generate the average and standard deviation.This number is important in providing a confidence level in anypredicted lost probability.

Correlation type 661 includes a description of the type correlationprovided. For example, the correlation may be between temperature andlocation. Correlation distribution 662 includes the type of distributionof the parameter sampled. For example, the result of the sampling maygenerate a normal curve, a uniform distribution, a bimodal normaldistribution, a Poisson distribution, etc. The remaining elements of therecord may vary depending on the distribution, but are described as ifthe sample distribution is a normal distribution. Correlation average663 includes the average of all the samples of the correlation.Correlation standard deviation 664 includes the standard deviation ofall the samples of the correlation. Correlation number 665 includes thenumber of samples used to generate the average and standard deviation.This number is important in providing a confidence level in anypredicted lost probability.

The type of information stored in each of the above described databasescan vary significantly depending on the type of environmental parameterssampled, the configuration of the loss prevention system, and thestatistical analysis performed. Many other types of information can begathered and utilized for predicting whether the mobile device may belost.
